Extensive research has yielded a crane having best-in-class reach with a boom that’s lighter and longer than its predecessor and capable of lifting heavier loads

Manitowoc will feature a new Grove rough-terrain crane at its booth for bauma 2016: the all-new GRT8100, which features class-leading capabilities and Manitowoc’s Crane Control System (CCS). The event takes place in Munich, Germany, April 11-17.

Debuting Grove’s new naming system (GRT= Grove rough-terrain), the GRT8100 is a generational update to the popular RT890E model. The new crane possesses a number of features that will enable it to lead its capacity class and deliver a better return on investment to owners.

“This new Grove model reflects everything we’ve learned in the last decade of crane design,” said Mike Herbert, global product director of rough-terrain cranes at Manitowoc. “For example, customers will find the new crane more reliable thanks in part to the advances brought by our Product Verification Centre (PVC). Each component has undergone extensive component validation and prototype testing and with that knowledge, we’ve been able to improve the GRT8100 from the ground up.”

The 90 t Grove GRT8100 will have exceptional reach with its 47 m boom that has a maximum tip height of 49 m. With a full complement of boom extension and insert options, the crane will also have best-in-class reach up to 77 m. The boom is lighter and longer than its predecessor, but has the ability to lift heavier loads throughout the load chart. Capability such as this will allow customers to get unparalleled usage out of a 90 t RT crane.

With increased capacity at mid-range and maximum radii, the GRT8100 is more versatile than competitors’ cranes – it boasts up to 16 per cent greater capacity at full radius, 13 per cent greater capacity in mid-range applications and 27 per cent greater capacity at close radii. With offsettable boom and fly extensions, the crane enables customers to lift heavier loads to greater heights, helping companies compete for – and win – bids for projects they may not have been able to previously.

The GRT8100 will be the only crane in its class to offer a hydraulic luffing boom extension. The bi-fold hydraulic boom extension can be configured to 10 m to 17 m lengths. Other optional boom extensions for the GRT8100 include a 10 m – 17 m manual offsettable bi-fold boom extension with fixed offsets at 0, 20 and 40 degrees as well as a heavy-duty 3 m jib that is offsettable to 40 degrees.

A new boom extension stowage system for both the GRT8100’s hydraulic and offsettable jib options decreases erection and stowage time by 60% when compared with previous generation Grove cranes.

This enables operators to set up and disassemble the crane in less time, saving money and increasing return on investment.

The GRT8100 will also have best-in-class line pulls at 7,883 kg on both the main and the auxiliary hoists. The stronger pull results in fewer parts of line being needed to lift loads, which will lead to increased productivity on the job site and faster customer payback.

“The GRT8100 will surely increase ROI for customers as it has a longer boom that is able to lift heavier loads,” Herbert explained. “Also its hydraulics are designed with efficiency and improved fuel economy in mind. Combined with the heightened reliability improvements brought by our PVC, the new crane will enable customers to be more efficient and versatile. Rental companies will surely see this benefit, too, as they will generate better rental rates from the GRT8100.”
